Exception handling

• In case a call is performed that could throw an exception, exception handling must be provided.

• In case a try block allocates resources, resource cleanup must be provided in a finally block.

  Note

  The usage of a using clause is preferred.

• When an IDisposable object is used, the object should be declared and instantiated in a using statement. The using statement ensures that the Dispose method is called (whether an exception occurred or not).

  Note

  The object is read-only and cannot be modified or reassigned.

• Every method serving as an entry point in a QAction should contain exception handling, so that it cannot throw exceptions. This is because otherwise a memory leak can occur in the SLScripting process.

• The ToString method of the exception object should be used when exception-related information is logged (instead of the Message property).

    protocol.Log("QA" + protocol.QActionID + "|Method Name|" + e.ToString(), LogType.Error, LogLevel.NoLogging);
